Gang, Since I "parked" this '75 PB around 8 + years ago, our ever-vigilant
EPA has taken leaded fuels off the market. The factory 455 was designed
around tetraethyl leaded fuels.
Can someone point me toward a FAQ in one of these lists discussing what one
must do to wean the 455 off leaded gas and get her to drink the new fuels?
Thanks

Can I also assume that the hardened value seats were in all the GMC
years -- including '73 ???????

I am not sure on the 75 but the 76 onan will run on unleaded. all GMC were
built to run on unleaded gas.

Tom,
Muchas gracias. Good info.
BTW, I'll make you such a deal on that case of lead substitute I bought 5
years ago when the thought of bringing her back from the dead crossed my
alleged mind.

Tom, Stupid question: How 'bout the Onan genny? One would assume that GM
would not put in a generator incapable of imbibing the same fuel as the main
mill, right?
